[0036] The embodiments of the present utility model will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and cannot be understood as a limitation of the present utility model.

[0037] The sunshade device 100, vehicle and control method of the sunshade device 100 according to embodiments of the present utility model will be described below with reference to Figures 1-4

[0038] The sunshade device 100 according to the first aspect embodiment of the present utility model, with reference to​Figures 1-4 The sun visor 10 and the dressing mirror 50 are connected.

[0039] The sun visor 10 comprises a first plate body 21, a second plate body 22 and an adjusting layer 23, the adjusting layer 23 is located between the first plate body 21 and the second plate body 22 and has an adjustable light transmittance, and the first plate body 21 and the second plate body 22 are both light-transmitting pieces. By adjusting the light transmittance of the adjusting layer 23, the adjusting layer 23 can be adjusted to filter sunlight to meet the needs of different users in different sunlight environments. In addition, the adjusting layer 23 has a certain light transmittance, so that the user can see the road conditions outside through the adjusting layer 23, avoiding the adjusting layer 23 blocking the line of sight. At the same time, the visual effect is comfortable and the sunlight is not directly incident into the eyes, and the field of view of the user when using the sun visor 10 is expanded, improving the driving safety. By making the sun visor 10 comprise the first plate body 21 and the second plate body 22, and the first plate body 21 and the second plate body 22 are both light-transmitting pieces, the influence of the first plate body 21 and the second plate body 22 on the light transmittance of the sun visor 10 as a whole is low. In addition, the adjusting layer 23 can be protected to avoid being scratched and damaged.

[0040] In some embodiments of the present application, the first plate body 21 and the second plate body 22 are preferably transparent pieces, so as to better avoid the sun visor 10 blocking the line of sight. In other embodiments, the first plate body 21 and the second plate body 22 can also have a color specially used for filtering light, so as to filter light according to the design needs.

[0041] For example, when the sunlight outside the vehicle is sufficient and the sunlight angle is directly incident into the eyes, the light transmittance of the adjusting layer 23 can be reduced to improve the visual comfort of the user, avoid the danger of too strong sunlight directly incident into the eyes, and because the adjusting layer 23 can transmit light and the first plate body 21 and the second plate body 22 are both light-transmitting pieces, the user can see the environment outside through the sun visor 100, improving the safety of driving.

[0042] For example, when the sunlight outside the vehicle is weak or the angle of the sunlight is not directly incident into the eyes, the light transmittance of the adjusting layer 23 can be increased, so that the user can see the environment outside more clearly through the sun visor 100, improving the safety of driving.

[0043] The sun visor 10 comprises a first area 24 and a second area 25, the adjusting layer 23 comprises a first adjusting layer 26 arranged in the first area 24 and a second adjusting layer 28 arranged in the second area 25, the dressing mirror 50 is arranged in the first area 24, and the dressing mirror 50 has light transmission and light reflection, and the light transmission and the light reflection of the dressing mirror 50 are both related to the light transmission rate of the first adjusting layer 26. When the light transmission rate of the first adjusting layer 26 is greater than or equal to a first transparency threshold, the dressing mirror 50 has light transmission; when the light transmission rate of the first adjusting layer 26 is less than the first transparency threshold, the dressing mirror 50 has light reflection. For example, the first transparency threshold can be 60%. By controlling the first adjusting layer 26 and the second adjusting layer 28, the sunshade function and the dressing mirror function can be independent and not affected, and the function area is more obvious.

[0044] Specifically, the first adjusting layer 26 and the second adjusting layer 28 can be independently controlled by two controllers, and the efficiency of independent control is higher; or the two adjusting layers can be controlled by a centralized controller by transmitting different control signals, so that the control cost is reduced. The dressing mirror 50 is a high-transmission high-reflection mirror, when the light transmission rate of the first adjusting layer 26 is greater than or equal to the first transparency threshold, the dressing mirror 50 has light transmission, and the light transmission effect is realized; when the light transmission rate of the first adjusting layer 26 is less than the first transparency threshold, the dressing mirror 50 has light reflection, and the mirror effect is realized.

[0045] For example, when the light transmission rate of the first adjusting layer 26 increases, the dressing mirror 50 has light transmission; when the light transmission rate of the first adjusting layer 26 decreases, the dressing mirror 50 has light reflection.

[0046] For example, the user can enable the dressing function of the sunshade device 100, the light transmission rate of the first adjusting layer 26 decreases, at this time, the dressing mirror 50 has light reflection, and the light transmission rate of the second adjusting layer 28 can be independently adjusted, so that the user can clearly see the external environment without being directly irradiated by sunlight.

[0047] According to the sunshade device 100 of the embodiment of the utility model, by making the sunshade device 100 comprise the adjusting layer 23 with adjustable light transmission rate, the sunshade device 100 can change the light transmission rate, the sunlight can be adjustedly filtered, and the line of sight can be avoided to be shielded, so that the user's visual effect is comfortable, the visual range of the user when using the sun visor 10 is enlarged, and the driving safety is improved. Furthermore, by controlling the first adjusting layer 26 and the second adjusting layer 28, the sunshade function and the dressing mirror function can be independent and not affected, the function area is more obvious, and the sunshade function and the dressing function can be better exerted and used.

[0048] According to some embodiments of the utility model, refer to Figure 1When the sunshade device 100 is closed for the dressing function, the dressing mirror 50 is translucent; when the sunshade device 100 is open for the dressing function, the dressing mirror 50 is reflective. The light transmittance of the first adjustment layer 26 is lower when the sunshade device 100 is open for the dressing function than when it is closed. By making the light transmittance of the first adjustment layer 26 lower when the sunshade device 100 is open for the dressing function than when it is closed for the dressing function, the light transmittance of the first adjustment layer 26 is lower when the sunshade device 100 is open for the dressing function, allowing the dressing mirror 50 to be reflective and thus function as a mirror; when the sunshade device 100 is closed for the dressing function, the light transmittance of the first adjustment layer 26 is higher, allowing the dressing mirror 50 to be translucent and thus avoiding obstruction of vision.

[0049] According to some embodiments of this utility model, refer to Figure 1 When the sunshade 100 is deactivated for vanity functions, the assembly formed by the first adjustment layer 26 and the vanity mirror 50 adjusts the light intensity after passing through the sunshade 10 to less than or equal to a first light intensity threshold; the second adjustment layer 28 adjusts the light intensity after passing through the sunshade 10 to less than or equal to a second light intensity threshold. For example, both the first and second light intensity thresholds are less than or equal to 40 cd, such as the range of the first light intensity threshold being 30 cd to 40 cd, and the range of the second light intensity threshold being 30 cd to 40 cd. When the external light intensity is high, the external light entering the vehicle is filtered by the sunshade 10, reducing the light intensity and thus lowering the light intensity entering the eyes, improving the user's visual comfort, preventing excessive sunlight from directly hitting the eyes and causing danger, and allowing the user to see the external environment more clearly through the sunshade 100, improving driving safety.

[0050] Among them, light intensity refers to luminous intensity, that is, the luminous flux emitted by a light source in a specific direction. Its unit is candela, abbreviated as cd.

[0051] In some embodiments of this utility model, when the sunshade device 100 disables the grooming function, the first adjustment layer 26 can adjust its transmittance in real time according to the light intensity. That is, when the light intensity increases, the transmittance of the first adjustment layer 26 decreases, thereby blocking more strong light; when the light intensity decreases, the transmittance of the first adjustment layer 26 increases, thereby making the user's field of vision clearer. The second adjustment layer 28 can also adjust its transmittance in real time according to the light intensity. That is, when the light intensity increases, the transmittance of the second adjustment layer 28 decreases, thereby blocking more strong light; when the light intensity decreases, the transmittance of the second adjustment layer 28 increases, thereby making the user's field of vision clearer. Through the real-time adjustment of the transmittance of the first adjustment layer 26 and the second adjustment layer 28, light can be provided according to the user's needs based on the light intensity in real time.

[0052] In some other embodiments of the utility model, when the sunshade device 100 closes the dressing function, the first adjusting layer 26 does not need to adjust the light transmittance in real time according to the light intensity, but sets two states of sunshade and light transmission. When the light intensity is greater than the external light intensity threshold, for example 60cd, the first adjusting layer 26 plays the role of shielding sunlight, and the light transmittance of the first adjusting layer 26 is adjusted to the first light transmittance, for example 20% light transmittance;When the light intensity is less than the external light intensity threshold, for example 60cd, the first adjusting layer 26 plays the role of enhancing the field of view, and the light transmittance of the first adjusting layer 26 is adjusted to the second light transmittance, for example 60% light transmittance, and the second light transmittance is greater than the first light transmittance. The second adjusting layer 28 does not need to adjust the light transmittance in real time according to the light intensity, but sets two states of sunshade and light transmission. When the light intensity is greater than the external light intensity threshold, for example 60cd, the second adjusting layer 26 plays the role of shielding sunlight, and the light transmittance of the second adjusting layer 28 is adjusted to the third light transmittance, for example 20% light transmittance;When the light intensity is less than the external light intensity threshold, for example 60cd, the second adjusting layer 28 plays the role of enhancing the field of view, and the light transmittance of the second adjusting layer 28 is adjusted to the fourth light transmittance, for example 60% light transmittance, and the fourth light transmittance is greater than the third light transmittance. By adjusting the light transmittance of the first adjusting layer 26 to the first light transmittance or the second light transmittance according to the light intensity, the shielding sunlight function or the field of view enhancement function of the first adjusting layer 26 can be realized, and the cost can be saved;By adjusting the light transmittance of the second adjusting layer 28 to the third light transmittance or the fourth light transmittance according to the light intensity, the shielding sunlight function or the field of view enhancement function of the second adjusting layer 28 can be realized, and the cost can be saved.

[0053] According to some embodiments of the utility model, refer to Figure 1 When the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 is greater than that of the second adjusting layer 28. Since the first adjusting layer 26 is superimposed with the dressing mirror 50, the light that transmits through the first adjusting layer 26 enters the human eye again through the dressing mirror 50, so that the overall light transmittance of the first area 24 is reduced. By making the light transmittance of the first adjusting layer 26 greater than that of the second adjusting layer 28, the brightness gap of the light that transmits through the first area 24 and the second area 25 when entering the human eye can be avoided, and the light intensity difference of the light that transmits through the first area 24 and the second area 25 is reduced.

[0054] According to some embodiments of the utility model, refer to Figure 1The absolute value of the difference between the first light intensity threshold and the second light intensity threshold is less than 5 cd, for example, the difference between the first light intensity threshold and the second light intensity threshold can be 0. For example, the first adjusting layer 26 can be made to have the same light transmittance as the second adjusting layer 28 in the second sun-shading state when the first adjusting layer 26 is combined with the dressing mirror 50 in the first sun-shading state. By making the absolute value of the difference between the first light intensity threshold and the second light intensity threshold less than 5 cd, the light intensity passing through the first area 24 and the second area 25 can be made substantially the same, so that the brightness of the outside world seen by the user through the first area 24 and the second area 25 is substantially the same when the user uses it, improving the user's visual experience.

[0055] According to some embodiments of the present application, referring to Figure 2 The first plate body 21 and the second plate body 22 are both glass pieces. By making the first plate body 21 and the second plate body 22 both glass pieces, the light transmittance of the first plate body 21 and the second plate body 22 can be made higher, reducing the impact of the first plate body 21 and the second plate body 22 on the overall light transmittance of the sun-shading device 100; and the cost can be reduced.

[0056] For example, the first plate body 21, the first adjusting layer 26 and the second plate body 22 are connected by transparent adhesive; the first plate body 21, the second adjusting layer 28 and the second plate body 22 are connected by transparent adhesive.

[0057] According to some embodiments of the present application, the adjusting layer 23 is an electrochromic layer. By making the adjusting layer 23 an electrochromic layer, the light transmittance of the adjusting layer 23 can be changed by energizing the adjusting layer 23, making it more convenient for the user to change the light transmittance of the adjusting layer 23. For example, the light transmittance of the adjusting layer 23 can be changed by energizing the adjusting layer 23 relative to when it is not energized. When the adjusting layer 23 is energized, the light transmittance of the adjusting layer 23 can be further adjusted by controlling the size and / or direction of the current.

[0058] According to some embodiments of the present application, the sun-shading device 100 is installed on a roof trim or a front windshield. When light from outside the vehicle passes through the front windshield and enters the vehicle interior, the sun-shading device 100 can effectively filter the light and reduce its intensity. Specifically, the sun-shading device 100 is installed on the roof trim by fasteners, or is attached to the front windshield by adhesive.

The sunshade device 100, the first light sensor and the second light sensor are electrically connected with the controller. By making the first light sensor detect the light intensity and / or the direct light angle outside the vehicle, the second light sensor detect the light intensity inside the vehicle, and making the sunshade device 100, the first light sensor and the second light sensor electrically connected with the controller, the controller can control the light transmittance of the sunshade device 100 according to the direct light angle outside the room, the light intensity outside the room and the light intensity inside the room, and can provide a more comfortable driving effect for the user in different environments.

[0071] For example, the first light sensor is used for detecting the light intensity outside the vehicle, and the second light sensor is used for detecting the light intensity inside the vehicle. When the measured light intensity outside the vehicle is greater than that inside the vehicle, the controller controls the sunshade device 100 to rotate downward to start the sunshade device 100, and controls the light transmittance of the sunshade device 100 to decrease; when the measured light intensity outside the vehicle is less than that inside the vehicle, the controller controls the sunshade device 100 to rotate upward to close the sunshade device 100.

[0072] For example, the first light sensor is used for detecting the light intensity and the direct light angle outside the vehicle, and when the direct light angle outside the vehicle reaches a set range and the light intensity outside the vehicle reaches a set range, the controller controls the sunshade device 100 to rotate downward to start the sunshade device 100, and controls the light transmittance of the sunshade device 100 to decrease, the stronger the light intensity, the lower the light transmittance of the sunshade device 100, so that the user can obtain a more comfortable driving visual effect.

By adjusting the light transmittance of the first adjusting layer 26 and the second adjusting layer 28 in real time, light can be provided according to the light intensity and the demand of user in real time.

[0078] In some other embodiments of the utility model, when the sunshade device 100 closes the dressing function, the first adjusting layer 26 does not need to be controlled to adjust the light transmittance in real time according to the light intensity, but the sunshade and light transmittance of the first adjusting layer 26 are controlled. When the light intensity is greater than the external light intensity threshold, for example 60cd, the first adjusting layer 26 is controlled to play the role of shielding sunlight, and the light transmittance of the first adjusting layer 26 is adjusted to the first light transmittance, for example 20% light transmittance; when the light intensity is less than the external light intensity threshold, for example 60cd, the first adjusting layer 26 is controlled to play the role of enhancing the field of view, and the light transmittance of the first adjusting layer 26 is adjusted to the second light transmittance, for example 60% light transmittance, and the second light transmittance is greater than the first light transmittance.

By adjusting the light transmittance of the first adjusting layer 26 to the first light transmittance or the second light transmittance according to the light intensity, the shielding sunlight function or the field of view enhancement function of the first adjusting layer 26 can be realized, and the cost can be saved; by adjusting the light transmittance of the second adjusting layer 28 to the third light transmittance or the fourth light transmittance according to the light intensity, the shielding sunlight function or the field of view enhancement function of the second adjusting layer 28 can be realized, and the cost can be saved.

[0079] According to the control method of the sunshade device according to the third aspect of the utility model, the light transmittance of the second adjusting layer 28 is adjusted according to the external light intensity, so that the light intensity of the light passing through the sunshade plate 10 is reduced to a suitable intensity, the external strong light is reduced, the user's visual effect is comfortable, and the field of view of the user when using the sunshade plate is expanded; and the light transmittance of the first adjusting layer 26 is adjusted according to whether the dressing function of the sunshade device 100 is opened, so that the optical state of the dressing mirror is adjusted, the dressing function of the sunshade device 100 can be opened or closed by adjusting the light transmittance of the first adjusting layer 26 as needed, the sunshade function and the dressing mirror function are independent of each other and do not affect each other, the function is more obvious, and the sunshade function and the dressing function are better played and used.

[0080] According to some embodiments of the utility model, the light transmittance of the second adjusting layer 28 is adjusted according to the external light intensity, including:

[0081] According to the light intensity outside the vehicle, the light transmittance of the second adjusting layer 28 is adjusted in real time, so that when the light intensity outside the vehicle changes, the light entering the vehicle through the second adjusting layer 28 can be filtered and adjusted to the appropriate light intensity in real time.

[0082] For example, when the light intensity outside the vehicle increases, the light transmittance of the second adjusting layer 28 is reduced, so that the light can be reduced through the sun visor 10 to avoid strong light glare; when the light intensity outside the vehicle decreases, the light transmittance of the second adjusting layer 28 is increased, so that the light can reach the appropriate light intensity after passing through the sun visor 10, and the light is not too dark to cause unclear road conditions in front.

[0083] According to some embodiments of the present application, the light transmittance of the second adjusting layer 28 is adjusted in real time according to the light intensity outside the vehicle, including: adjusting the light transmittance of the second adjusting layer 28 in real time to adjust the light intensity passing through the sun visor 10 to be less than or equal to the second light intensity threshold. The light transmittance of the second adjusting layer 28 can be adjusted according to the light intensity outside the vehicle, and the light intensity passing through the sun visor 10 can be adjusted to be less than or equal to the second light intensity threshold, so that the light entering the vehicle can be reduced to the appropriate light intensity after passing through the second adjusting layer 28, which can make the light intensity sufficient to make the user clearly see the situation in front, and can also avoid the light being too strong to be dazzling.

[0084] The range of the second light intensity threshold can be 30cd-40cd.

[0085] According to some embodiments of the present application, the light transmittance of the first adjusting layer 26 is adjusted according to whether the sun visor 100 opens the dressing function, including:

[0086] When the sun visor 100 opens the dressing function, the light transmittance of the first adjusting layer 26 is adjusted to make the dressing mirror 50 have a reflective property, for example, the light transmittance of the first adjusting layer 26 can be adjusted to be less than or equal to the first transparency threshold;

[0087] When the sun visor 100 closes the dressing function, the light transmittance of the first adjusting layer 26 is adjusted to make the dressing mirror 50 have a light transmittance, for example, the light transmittance of the first adjusting layer 26 can be adjusted to be greater than the first transparency threshold, for example, the first transparency threshold can be 60%;

[0088] The light transmittance of the first adjusting layer 26 when the sun visor 100 opens the dressing function is less than the light transmittance of the first adjusting layer 26 when the sun visor 100 closes the dressing function.

[0089] By making the light transmittance of the first adjusting layer 26 when the sunshade device 100 opens the dressing function smaller than the light transmittance of the first adjusting layer 26 when the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 can be made lower when the sunshade device 100 opens the dressing function, the dressing mirror 50 has a reflective property and thus presents the function of a mirror; when the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 is higher, and the dressing mirror 50 has a light transmittance, thereby avoiding blocking the line of sight.

[0090] According to some embodiments of the present application, when the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 is adjusted to make the dressing mirror 50 have a light transmittance, comprising:

[0091] The light transmittance of the first adjusting layer 26 is adjusted to make the light intensity passing through the sunshade panel 10 adjusted to be less than or equal to the first light intensity threshold. For example, when the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 can be adjusted according to the light intensity outside the vehicle to make the light intensity passing through the sunshade panel 10 adjusted to be less than or equal to the first light intensity threshold. The range of the first light intensity threshold can be 30cd-40cd.

[0092] When the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 is adjusted to make the light intensity passing through the sunshade panel 10 adjusted to be less than or equal to the first light intensity threshold, so that the light entering the vehicle can be reduced to an appropriate light intensity after passing through the first adjusting layer 26, which can make the light intensity sufficient for the user to see clearly the situation in front, while avoiding the light being too strong and dazzling.

[0093] For example, the absolute value of the difference between the first light intensity threshold and the second light intensity threshold can be less than 5cd, so that when the sunshade device closes the dressing function, the light intensity difference between the first region 24 and the second region 25 of the sunshade panel 10 is small, so that the brightness of the outside world seen by the user through the first region 24 and the second region 25 is basically the same, improving the user's visual experience.

[0094] According to some embodiments of the present application, when the sunshade device 100 closes the dressing function, the light transmittance of the first adjusting layer 26 is controlled to be greater than the first transparency threshold. In this way, when the sunshade device 100 closes the dressing function, the first adjusting layer 26 can have good light transmittance, avoiding the first adjusting layer 26 from reflecting light due to low light transmittance and affecting the observation of the outside view.
